With reference to Fig. 1, Fig. 2, air purifier constitutes casing by upper box 4, lower box 2, cover plate 16.Casing bottom and base side have bar shaped

air inlet

13,14,15, are equipped with pre-filter screen 12, longitudinal electrostatic dust-collecting parts 11, molecular sieve adsorption parts 10, charcoal absorption parts 9, ultraviolet sterilization parts 8, electric fan 1 successively from the base to the top in casing.Bar shaped outlet 5 is arranged on the upper box 4 of casing top one side, and bar shaped air outlet 5 inboards are provided with negative discharge silk 3.Being provided with the air partition 6 that is fixed on the upper box 4 below the air outlet 5, be full of deadener 7 in the cavity between air partition 6 and the upper box 4.Longitudinal electrostatic dust-collecting parts 11 are in insulation frame 17, put the contour straight-through tube 21 of full and insulation frame 17, all are connected with discharge silk 20 in each straight-through tube 21 and are connected straight spring 19 with discharge silk 20.Straight-through tube 21 can be regular hexagon tube, square tube, parallelogram tube, cylinder.In straight-through tube 21 outlet air ends and between discharge silk 20 peripheries in the middle of it, be provided with inner core 22.As shown in Figure 3, Figure 4, molecular sieve adsorption parts 10 are at metal frame 25 and have fixed woven wire 26 up and down respectively, it is built-in has expired sodium-X type (10X) molecular sieve 23 or other dedicated molecular sieve used forming, molecular sieve woven wire 26 is idiostatic with straight-through 21 by metal frame 25, and flue dust is captured again.

Charcoal absorption parts 9 are to place fibrous in frame of plastic or Alveolate activated carbon capable 24 forms.Ultraviolet sterilization parts 8 are to be contained on the plastic frame by uviol lamp to form.Its cross sections such as the frame of plastic of longitudinal electrostatic dust-collecting device insulation frame 17, metal frame 25, charcoal absorption parts 9, ultraviolet lamp door are onesize, and after their insertion end plates 18, its frame kissing connects, and constitutes vertical air channel.As Fig. 5, shown in Figure 6, have many apertures 27 in the scope of the both sides proper width L of the line C of center of arc of air partition 6, to lower aerodynamic noise.

The course of work of the present utility model and function description are as follows: after connecting the 220V AC power, the straight-through tube 21 of longitudinal electrostatic dust-collecting parts 11, metal frame 25 and woven wire 26 with molecular sieve adsorption parts 10, just connect the high voltage direct current positive pole, discharge silk 20 and spring 19, negative discharge silk 3 are just connected the high voltage direct current negative pole.Straight-through tube 21 can be exchanged use with the high voltage direct current both positive and negative polarity of discharge silk 20, spring 19.After connecting power supply, electric fan 1 promptly starts working.Gas in the air purifier is discharged by bar shaped air outlet 5, and i.e. 13,14,15 inspirations of bar shaped air inlet below air purifier of indoor polluted gas are at first through pre-big dust, the drift of filter screen 12 eliminations; Then enter the straight-through tube 21 of longitudinal electrostatic dust-collecting parts 11, under the effect of high-voltage electrostatic field, powder, flue dust very easily become negative ions within it and by aggregation, can not captured by woven wire 26 by the anion of aggregation; Enter the gas of molecular sieve adsorption parts 10, the volatile organic solvent molecule of macromolecule wherein and some other pernicious gas molecules are adsorbed by molecular sieve 23; At this moment gas enters charcoal absorption parts 9 again, the stink in the gas, peculiar smell and partial C O, CO ₂Deng the further adsorption removal of pernicious gas quilt; Then gas kills wherein each kind of bacterium, virus by ultraviolet sterilization parts 8; Last gas is before bar shaped air outlet 5, and the effect through high voltage negative discharge silk 3 produces a large amount of negative oxygen ions, becomes pure and fresh pure air in 5 inlet chambers of bar shaped gas outlet.
